Common Green Wires as supplied Common ‘S’ & ‘W’ Plan ‘Y’ Plan Green Wire relocated for ‘Y’ Plan IFOS - In Flue Outdoor Sensor Kit - System Boilers 2.0 Introduction 1. The In Flue Outdoor Sensor - IFOS - kit positions a temperature sensor in the horizontal or vertical flue terminal. The flue system can be up to 4 metres of actual length, or a further 5 metres with the optional extension cable . Installation of this kit permits the customer to gain the efficiency benefits of outdoor weather temperature compensation control. The sensor allows the outdoor temperature to be taken into consideration and the boiler flow temperature regulated accordingly to provide required comfort levels. 2. The curve determining boiler flow temperature should be set as low as possible but still maintaining required comfort levels. The selected curve must be noted on the identifying label to be affixed to the boiler. 3. The addition of anything that may interfere with the normal operation of the appliance without express written permission from the manufacturer could invalidate this kit and the appliance warranty. In GB this could also infringe the Gas Safety (Installation and use) Regulations. 4. This kit is only suitable for use with the boiler ranges listed on page 2. The relay PCB supplied MUST be fitted to the system boiler to ensure correct operation. 5. A 230V switched live from the DHW cylinder thermostat (demand signal) must be connected to the spare position on terminal block M1 (Figs. 15 & 19). IMPORTANT: This kit is for use with horizontal & vertical flue terminals in a flue system of up to 4 metres actual length. A 5 metre sensor cable extension is available as an optional extra. The kit cannot be fitted where other devices such as the MULTIFIT GasSaver are incorporated into the flue system. It is permissible to shorten the cable. If shortening the cable DO NOT cut the sensor end ! Conventional Controls: Standard mains voltage ON/OFF controls do not affect the method of setting the curve or boiler operation when the IFOS is fitted. Conventional controls in conjunction with IFOS represent the simplest solution. When a DHW demand is applied to the boiler the Outdoor Sensor is overridden. OpenTherm Controls: If an OpenTherm control is also to be connected to the boiler this must be taken into consideration as some devices affect the operation of the boiler control knobs or buttons. Depending on the device used it is possible that the OpenTherm control will assume the role of “master”, rendering the boiler controls inoperative or altering their function. It is recommended that the IFOS is fitted and set prior to connecting any OpenTherm device. Consult the instructions supplied with such devices before setting the curve. The Baxi uSense device is recommended for this type of control application. IMPORTANT: The relay PCB is set up for ‘S’ or ‘W’ plan systems. For a ‘Y’ plan system change the green wire over on the relay PCB as shown below. 7730041-02 (7/19) 3

6.0 Setting the Sensor Curve 1. Ensure that there is power to the boiler (though it is not necessary for there to be a heating demand). 2. The Central Heating Control Knob should be turned clockwise (Fig. 21) to the position which corresponds with the desired curve as shown on the graph (Fig. 24). NOTE: The curves are given as examples in convenient increments of 10. It is possible to set the curve between these recommendations, e.g. at 62, but for clarity this detail is not shown on the graph . 3. Curve 50 is recommended as the most suitable for the normal range of conditions expected in the UK. Consider the type of dwelling and discuss with the user their requirements - one of the other curves may be more appropriate. For example, if Curve ‘40’ is selected (Fig. 24), at an outside temperature of 0°C the boiler flow temperature will be 80°C. Consider the type of dwelling and discuss with the user their requirements to determine the most appropriate curve. 4. Normally the display will show the current temperature of the water in the boiler (e.g. 41°C, Fig. 22). As the knob is turned the display will show the selected curve (Fig. 23). 5. Continue with the installation and commissioning of the boiler as described in the Installation & Service Manual. IMPORTANT: Explain to the user how the outdoor sensor regulates the boiler flow temperature for central heating and that Central Heating Temperature Control will NOT operate in the way as described in the boiler User Guide.
